Subject: [ClusterLabs Developers] Can stalled libqb SHM I/O delay
 Pacemaker's operation timer?
Message-ID: <CAGKCzNA4i=8X6VSMQjmAWO4mRozS0eipmVL0hjK2ttw1+YUs_w@mail.gmail.com>

Could Pacemaker?s controller block on a stalled block-device read while
faulting in a swapped-
out libqb SHM page, before it receives the executor reply and starts the
operation timer?

Is that expected?
